Thru Lines - new feature on ancestry

[Merry]

Trees uploaded or created through ancestry may or may not be accurate. Don't get me started on whether a 'professionally' created tree might or might not be more accurate than one worked on by a so-called amateur!!

I'm not sure what you mean by ancestry "relying" on people's tree research? Ancestry do not vet the trees they hold on their site and wouldn't know if a tree was 'professional' or otherwise. Individuals can choose to copy someone else's tree at their peril!
